Given numbers are 205,489,379,778,287

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 205,489,379,778,287 is 206909088330.

Find LCM of 205,489,379,778,287 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

41 x 5 x 489 x 379 x 778 x 7 = 206909088330

Therefore, the lowest common multiple of 205,489,379,778,287 is 206909088330.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

205 x 489 x 379 x 778 x 287 = 8483272621530

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

205 : 1, 5, 41, 205

489 : 1, 3, 163, 489

379 : 1, 379

778 : 1, 2, 389, 778

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,489,379,778,287, is 1.

Now, the common factors can be found like this.

205:5x 41

489:3x 163

379:379

778:2x 389

287:7x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

41 = 41

Therefore, the value for common factors is 41.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 8483272621530/(1x41)

LCM = 8483272621530/41

LCM = 206909088330

Thus, we can understand that the LCM of 205,489,379,778,287 is 206909088330.
